5.4 Prompt window

The prompt window will be displayed during the operation of the system when the system needs the user to confirm or to conduct some operations. This system has about 5 “prompt windows” that will be introduced below.

From bypass to inverter mode with interruption:

If the bypass voltage or frequency exceeds the synchronized range and utility voltage or frequency is normal, the inverter can’t be in synchronize with the bypass, and the output can only transfer to bypass after an interruption of about 15ms when the user press the “Start” key of inverter. Before transferring, the system should let the user to confirm whether the interruption can be accepted, as shown in Fig.5-40. Other operations can only be done after confirmation. If the bypass voltage restores to normal before the user makes confirmation, the UPS will transfer to inverter mode automatically. At the same time, the prompt window will disappear automatically.
